eReefs GBR4 River Tracers v4.0: Passive Tracer Results for 35 Rivers

35 significant rivers are tracked using passive tracer results derived from a 4km-resolution hydrodynamic model of the Great Barrier Reef. The model is forced by high-resolution atmospheric, ocean, tide, and river boundary data from Australian meteorological and oceanographic sources. This hindcast model, produced by the Australian Ocean Data Network, is considered the best available river tracer model results for its timespan.

Use Cases

• Modeling river plume dispersion in the Great Barrier Reef based on passive tracer results
• Assessing contributions to water quality for Reef Report Cards based on results for 35 significant rivers
• Validating hydrodynamic model outputs based on hindcast simulation data
• Analyzing the impact of river boundaries on marine environments based on stream flow and temperature data

Strengths

• Results are derived from a 4km-resolution regional-scale hydrodynamic model
• Model is forced by high-resolution atmospheric reanalysis (BARRA) and ocean reanalysis (BRAN2020) data
• Includes passive tracer results for 35 rivers of significance to a national water quality plan

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to the source models
